A circular value chain will show significant changes in the material flows associated with ROCKWOOL'S stone wool products.

• Firstly, the sourcing of raw material input would shift away from virgin and fossil material inputs, which results in an increase in the use of non- virgin and renewable materials.
• Secondly, non-virgin materials would increasingly come from ROCKWOOL's own reverse logistics and partnerships with other industries and waste management service providers.
• Thirdly, waste to landfill will decrease substantially as the recycling infrastructure for demolition waste improves, thus closing material loops.

ROCKWOOL's value chain can become fully circular.
The most impactful steps towards that ambition include shifting to a feedstock that consists entirely of non-virgin and renewable materials, advancing the development of reverse logistics and recycling infrastructure, and creating more high value products that are designed to profitably support the envisioned material cycles
